Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update can be installed. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
